Fell Sans

Fell Sans is a skeleton. He wears a perpetual smile, revealing sharp teeth, one of which is gold. His eyes have black sclera, within which are visible red, dimly glowing pupils. He wears a red sweater, over which he wears a black jacket with a warm fur hood. He wears black shorts with yellow stripes on the sides.

Fell Sans has a rude and cruel personality, but he rarely displays it, often interacting calmly with people, often with mockery. He is most serious with his brother, Papyrus, who constantly chides Sans for calling him "boss." Fell Sans enjoys drinking mustard, something his brother doesn't particularly approve of.
